Mastering Integer Addition Rules

This video tutorial covers the rules for adding integers, focusing on the same sign and different sign rules. It begins with an introduction to key vocabulary such as absolute value and integers. The same sign rule involves taking the absolute values of numbers, adding them, and keeping the common sign. The different sign rule requires taking absolute values, subtracting the smaller from the larger, and using the sign of the larger number. The lesson concludes with a word problem example and a reminder for students to practice and prepare for a mastery check.
